To all whom'z't may concern: 1

Be it known that I, JULIAN Gr. GOODHU'EA, a citizen of the UnitedStates, residing at Chicago, in the county of Cookand Stat of Illinois,have invented a certain new and useful Improvement in Rotary Valves, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to an improvement in rotary valves, thisapplication being a division of my copending application No. 663,322 fordisinfecting apparatus and the like, filed December '1, 1911. That partof my invention described and claimed herein has as its principal'objectthe provision of automatic means whereby one pipe maybe connected withany one of a plurality of other pipes. v I v A further object of myinvention resides in the particular arrangement and combination of partshereinafter described.

In the accompanying drawings Figure 1 is a vertical central section ofmy improved valve device;

Fig. 2 is a horizontal cross section on the line 22 of Fig. 1 looking inthe direction of the arrows;

Figs. 3, 4 and 5 are detail views of portions of my device.

Referring more particularly to the draw ings, 1 is a cylindrical casingsurrounding the valve device proper which mayor may not be used asdesired. The casing 1 is shown as attached to a wall by suitable screwsand provided at its lower end with fittings connecting with conduits'such as 22. In the conduits 2-2 are pipes 3 3 which connect directlywith my valve device. One of these pipes, which I will call the inletpipe, enters the lower end of the valve casing through the center of acasting at the top for purpose to be mentioned later.

lVithin the cylinder 5 is a valve structure shown in detail in Fig. 3comprising a central bolt.7 which carriesintermediate of its ends acupleather 8, the cup leather 8 being clamped between suitable nuts such as99. At the. ends of the bolts 7 are nuts orhubs provided with aplurality of projecting arms such as 10. Each of these arms 10 isprovided with an inclined face 11. Surrounding the valve cylinder 5 is acasting 12, which is provided with a plurality of openings 13 in itslower face for connection with the pipes 3-3. This casting is alsoprovided with a series of horizontal passages such as 14 connecting saidopenings with apertures in the casing 5. As is clearly illustrated inFig. l, the cup leather 8 is provided with an aperture 15 by which theinterior of the casing 5 may be connected with the passages 14throughthe apertures in the casing and thence with the pipes 8. Asplainly shown in Figs. 1 and 5 the castings '4 and .6 are provided withindentation'sor serrations 16 along their inner edges.

In the operation of my device it is eX- originalapplication, of whichthis is a division, the inlet pipe is shown as connected with a doorcheck, but it is obvious that the principal source of pressur orpulsation is immaterial.

Referring now to Fig. 1, the valve member is shown at the upper end ofthe casing 5. If now the pressure in the lower part of the casing fallsbelow atmospheric, the valve will be forced down so that the inclinedfaces 11 of the arms 10 will strike against th inclined surfaces of theindentations 16 on the member 4. The valve member will consequently berotated to some extent. If now the partial vacuum of the valve casing issucceeded by a pressure impulse coming from the inlet pipe the valvemember will b forced to the top of the casing again, whereupon the upperarms 10 will engage in the indentations on the when looked at from thesame direction. Consequently when the members 4 and 6 are placedopposite to each other, the impulses given the bolt are in the samedirection. As appears in Fig. 3 the inclination of the faces 11 on thearms at the opposite ends of th bolt 7 is in the opposite direction whenviewed from the side of the bolt 7 in order to properly cooperatewiththe indentations on the members it and 6. By the means described and inresponse to the pulsations mentioned the port 15 will be connected witheach of the passages 14 in turn.

As is well known the door check produces alternate periods of pressurand partial vacuum. Consequently I have shown my device as operated byatmospheric pressure on the down stroke. This is not essential, however,since the down stroke might be accomplished by means of a spring orweight, the device thus being adapted for use in connection with systemsin which the pressure would never fall below atmospheric, but wouldmerely have periods of alternately high and low pressure.

It will be obvious also that while I have shown and described herein arotating valve having only one port therein surrounded by a castinghaving six corresponding passages any convenient number of ports may beused in the valve to cooperate with a suitable number of passages in thesurround ing casting. Certain other possible combinations of ports andpassages are shown and described in my original application.
